Answer: 1. Han run 2.5 miles after a half hour.
2. No, they will not meet within 1 hour.
Step-by-step explanation:
Here, Han runs at a pace of 12 minutes per mile.
Or, we can say that he can run with the speed of 5 miles per hour. (because, speed = 1/pace and 12 minutes = 1 miles ⇒ 60 minutes = 5 miles)
Similarly, If Tyler runs at a pace of 15 minutes per mile ⇒ Tyler run with the speed of 4 miles per hour.
Therefore,
1) The distance covered by Han in half an hour = 1/2 × 5 = 2.5 miles
(because distance = speed × time)
Now, 2) the time at which Han and tyler will meet,
T= Total distance/ ( the sum of their speed)
⇒ hours > 1 hour
That is, they will not meet within 1 hour.
